A recent synthesis paradigm for tailoring the far-field radiation of leaky wave (LW) radiating metasurface (MTS) antennas is reviewed and experimentally validated. The considered antennas are realized with electrically small patches printed on a planar grounded dielectric slab. The patch layer is modeled as an impedance sheet whose spatial variation is initially designed to provide the desired LW effect from a prespecified surface wave (SW) excitation.

基于表面波的超表面天线设计的直接数值反演方法：基础知识、实现和前景


回顾并实验验证了最近用于定制漏波（LW）辐射超表面（MTS）天线远场辐射的合成范例。所考虑的天线是通过印刷在平面接地电介质板上的电小贴片来实现的。贴片层被建模为阻抗片，其空间变化最初设计为通过预先指定的表面波 (SW) 激励提供所需的 LW 效应。
